Great for hot weather and for hard working engines

And if you take advantage of the oils ability to take care of your engine for extended oil change periods, it is the most economical. Buy oil filters designed specifically for synthetic oil and extended oil change periods and you can safely change oil every 10,000 miles. If you install a bypass oil filter in addition to your regular spin on filter you can extend your oil change periods even further. On my truck and car I change the element in my bypass filter every 5000 miles. I change my spin on filter every 10,000 miles. I also send a small sample of my oil to an oil testing lab at regular intervals to determine if I need to change oil and to determine the health of my engine. I have purposely not endorsed any products other than this oil so you can do your own research.

A very good inexpensive motor oil for motorcycles

A very good motor oil for my motorcycles. Inexpensive compared to other top end brands. Whenever I change my oil (about 3k to 5k miles), the old oil is very clean and I have never seen any metal particulates. Im sure other oils do the same job but the price sets Rotella apart.

Good oil Poor Packaging

The oil is outstanding!! Your packaging is horrific!! Three separate 1 gal containers in a large box no packaging the box was torn open!! I am not sure what training you give your technician on boxing but they need to be retrained!! Again oil awesome but packaging is disappointing
